Generalizations of Rough Sets: From Crisp to Fuzzy Casesities of generalized rough sets based on those two different interpretations. We describe the relations between generalized rough sets and types of extracted decision rules. Moreover, we extend the discussion to fuzzy rough sets. Through this paper, the relations among generalized crisp rough sets a

A Comparative Study of Formal Concept Analysis and Rough Set Theory in Data Analysisnstructed. Formal concept analysis focuses on concepts that are definable by conjuctions of properties, rough set theory focuses on concepts that are definable by disjunctions of properties. They produce different types of rules summarizing knowledge embedded in data.

Structure of Rough Approximations Based on Molecular Lattices rough set theory using algebra systems has been paid great attention, and some researchers had reported significant developments. But the base algebra systems, on which approximation operators are defined, are confined to special Boolean algebras, including set algebra and atomic Boolean lattice. T

Rough Approximations under Level Fuzzy Setsrepresentations. In this paper, we study rough approximations based on the notion of level fuzzy sets. Two rough approximation models, namely .-level rough set and .-level rough set, are proposed. It shows that .-level fuzzy rough set model can approximate a fuzzy set at different precisions.
